  • A great budget purifier with AUTO feature!
Style: 411 Auto
Having an AQI sensor with an auto mode is pretty rare for purifiers at this price range. BlueAir is really cool for creating something inexpensive to be a set it and forget. I’ve tested and tried many different air purifiers and while I have a favorite already, this one really deserves its praises. For starters, I want to say this is definitely a bedroom-centric purifier and isn’t meant for larger open concept spaces (Opt for the 311 Auto for bigger area). The 411 auto is virtually silent on level 1. Level 2 is also pretty quiet but has a very gentle breeze sound (personally my fav for sleeping bc the white noise is calming). Level 3 definitely is a jump in sound but is good for brief quick air cleaning. Auto mode is pretty accurate with detection rate. I put out a candle that was relatively close proximity to the purifier and the sensor light turned red and gradually revved up to sift out the smoke. In another test, I blew out a candle that was further away from the purifier across the room. The sensor did take longer to begin revving up the fan (about 5 mins give or take) but nonetheless still managed to detect. I find dissipation of odors and smoke to be pretty decent. Today I was indecisive about outfits and tried on many diff things while looking in the mirror and I guess all the dust and lint kicked up and got the little guy revving up. All this to say, the AQI sensor and Auto Mode is great! Other positives: -low power consumption. It’s gonna be so inexpensive on your electricity bill. Only 10watts of power max! -stylish! The prefilters are very attractive I’m in a very modern minimalist space with black and whites and grays. The default pre filter it ships with fits perfectly! Diff decor? They have many different colors for you. I have to say, I doubted this thing for a bit because of its seemingly lacking power. It reminded me a lot of the Levoit Vista 200. However that model is awfully weak and not worth the money. I believe the reason why the Blue Pure 411 Auto works so efficiently well, is because it is 90% filter. There’s no plastic unibody or restrictive intake grills. Just fabric and filter. Because of this, less fan power is needed to pull in air through several layers of plastic holes and super dense materials. Pretty innovative and a true example of “less is more”. Highly recommend for those who want a stylish, efficient minimalist air purifier for a small space. ... show more

  • Quiet, compact, effective
Style: 511
As someone with allergies, I have had more than my fair share of air purifiers. This is one of the best, most quiet for single room use. I originally ordered a used air purifier, but it came with an off-putting smell. The lights on top are unobtrusive, but are less helpful than simply listening to the sound of the air purifier as you push the button, since there are no indicators with the lights. Aside from that, the unit sips electricity, is simple to operate, battles allergies effectively, but probably isn't worth the 50% price premium over the mini. ... show more

  • The best air filter on the market
Style: 511
I have purchased multiple air filters to control, allergies and other bits of particles in the air That two of my family members are sensitive to. I purchased my first one three years ago and it still works as well as it did when it was new. I bought a second one recently from Amazon and it’s exactly the same quality, easy of use quiet, and genuinely changes the quality of the air, removing all of those particles. This is the only air filter I will ever buy in the future, having tried other brands. They don’t measure up to the quality of this one, not even close. I would recommend anyone who is looking for an air filter buy only this brand. Any other product will be a wasted your money and you’ll end up replacing it in a year ... show more

  • Difficult to understand use, no clear on and off
Style: 511
I like the effectiveness of this air purifier so as far as performance goes, I think it should have five stars. Since there’s no way of testing air quality and we just have to go on faith, I’m guessing that it’s a good quality machine. However, clearly it was designed with aesthetics in mind and not practicality. It’s difficult to turn on an off or to know how to turn it higher or lower. You do this with a series of taps on the top ring. It’s very Star Trek in a very unnecessary way. I love Star Trek. I love everything about Star Trek. I don’t think even they would’ve kept this on the enterprise because it’s too annoying to use , however, having said that I just turned mine on low and keep it on all the time. I have noticed that environmental allergies bother me much less this year. If you are into the super modern look and have the gray walls that all designers think everyone should have now, you might love this look and usage facility might not bother you. I don’t think an older person would be able to use this easily. The only thing that lets you know if it’s on or off is a light that shines for a moment when you tap it. There is delay in the action so you don’t know if you’ve actually turned it up higher or turned it off for a few seconds, so if you’re impatient like me and tap it again, you’ll probably accidentally turn it off and have to start all over again . Again, weird design, leaving you confused. Is very silent and that’s a big plus. It probably deserves one more star, but I’m too annoyed with the lack of the on and off clarity to increase my stars. Here’s an idea, how about somebody make a vintage looking air purifier with simple on off switches, make it look like a vintage radio. I bet that would be a big seller, the nice old-fashioned knobs. On and off. I have no idea how I’m going to change the filter when it’s time to change it, the whole thing is a mystery as to how it’s assembled, and I wish they would just include a few extra filters with the purchase so then you weren’t trying to figure out what kind of machine you have and which kind of filters to buy six months later. I’d be willing to pay extra to have the extra filters delivered with the purchase. If I sound annoyed it’s because I am. But I’m sure the machine is good quality. Updated review 9/11/24: The machine is actually silent on low. It’s been on all day and I didn’t even know it. You literally cannot hear it at all on its lowest setting. It also did a great job getting rid of a smell that was from something burned in my kitchen. So it is a very effective machine. I also now am wondering if the thing that I found fault with is actually a benefit to older people with arthritis if they cannot turn a knob, then just tapping the top might be very helpful to them. In fact, anyone with mobility issues could put this beside their bed and just tap it at night in the dark and it would be easy to use for them. Because it is silent, it will not work for you as a white noise machine. I’m now going to add a star. Xo ... show more

  • Quiet Little Purifier
Style: 511
So far, this BLUEAIR small purifier is working well. The air in the bedroom seems to be cleaner. It is quiet and does not disturb our sleep. In the future, we will get a couple of others for our guest bedrooms.

  • Perfect for baby
Style: Mini Max
Some reviews state the fan can be loud, but we actually prefer it on high because it creates enough white noise to soothe and relax the babies. First time we went to clean the filter there was a ring of dust around the unit so we knew it was working overtime.
